In this post, I explain how to use an online file storing and sharing service like AARNet’s CloudStor (but any WebDAV service will do) to access and update your Zotero library from different computers.
Release 0.3.3 of the RPushbullet package just got to CRAN. RPushbullet offers an interface to the neat Pushbullet service for inter-device messaging, communication, and more. It lets you easily send (programmatic) alerts like the one to the left to ...
reticulate allows us to toggle between R and python in the same session, callling R objects when running python scripts and vice versa. When calling R data structures in python, the R structures are converted to the equivalent python structures where applicable. However, like translating English to Mandarin, translating R structures to python may not […]
Previously in this series: The “lost boarding pass” puzzle The “deadly board game” puzzle The “knight on an infinite chessboard” puzzle The “largest stock profit or loss” puzzle The “birthday paradox” puzzle I have an interest in probability puzzles and riddles, and especially in simulating them in R. I recently learned about Feller’s coin-tossing puzzle, […]
What is an Rprofile Every time R starts, it runs through a couple of R scripts. One of these scripts is the .Rprofile. This allows users to customise their particular set-up. However, some care has to be taken, as if this script is broken, this can cause R to break. If this happens, just delete […]
We are excited to announce the nse2r package. NSE (National Stock Exchange) is the leading stock exchange of India, located in the city of Mumbai.

Although R is great for quickly turning data into plots, it is not widely used for making publication ready figures. But, with enough tinkering you can make almost any plot in R. For examples check out the flowingdata blog or the Fundamentals of Data Visualization book. Here I show five charts from the lay press […]
Podcasting has gotten quite a bit easier over the past 10 years, due in part to improvements to hardware and software. I wrote about both how I edit and record both of my podcasts about 2 years ago and, while not much has changed since then, I thought it might be helpful if I organized […]
Clint Johns writes: I’m a regular visitor to your blog, so I thought you might be interested in this link. It’s a relatively recent article (from 7/12) about Donald Westlake and his long career. For my money, the best part of it is the generous number of Westlake quotations from all sorts of places, including […]
Bert Gunter writes: This link is to an online CNN “analysis” of school shootings in the U.S. I think it is a complete mess (you may disagree, of course). The report in question is by Christina Walker and Sam Petulla. Gunter lists two problems: 1. Graph labeled “Race Plays A Factor in When School Shootings […]
Ulrich Atz writes in with a question: A newcomer to Bayesian inference may argue that priors seem sooo subjective and can lead to any answer. There are many counter-arguments (e.g., it’s easier to cheat in other ways), but are there any pithy examples where scientists have abused the prior to get to the result they […]
